Summary: Preserve Opportunistic Containers when
"findLostContainer"
Key: YARN-10768
URL: https://issues.apache.org/jira/browse/YARN-10768
Project: Hadoop YARN
Issue Type: Improvement
Reporter: Zhengbo Li
Assignee: Zhengbo Li
The `findLostContainers` method in `RMNodeImpl` is designed to detect any
containers that are not running but failed to report its complete status to RM.
However the current implementation *always considers O containers as lost*.
This has result performance issues for us because we use Opportunistic
Containers heavily in our feature.
